- Rhaetina gregaria, one of the most common Late Triassic brachiopod species, has been regarded as a survivor that ranges across the Triassic-Jurassic boundary into the Early Jurassic. The external morphology of specimens from before and after the Triassic–Jurassic extinction event were initially thought to be identical. Study of the internal features of the early Jurassic material showed that it was actually quite distinct from the Triassic specimens, and should be assigned to the genus Lobothyris as L. subgregaria.[4]
- The flightless bird related species reinhabited the island, from which the modern white-throated rail evolved, where it is found to the present day.[5]
